Hi, if a week is a long time in politics, a day is a long time in business at the moment,

and it can be exhausting trying to keep up with all the latest developments.

That's why we've interrupted your Business Daily pod feed to bring you Business Weekly,

a new weekend programme which brings you an hour of the most interesting, inspiring and thought-provoking stories you might have missed

from the BBC's business team.

Hello and welcome to Business Weekly with me, Vashala Sripathma. This week we explore the

world of microbes, the industry that recreates what we can't necessarily touch or feel.

Anything from smells to viruses can be recreated by biotechnology.

And whilst these genetically modified microbes could herald a new industrial revolution,

it poses new dangers as well, as my colleague Manuel Sari Gossa has been finding out.

This perfumery in central London sells a wide range of scents. The shelves are stacked with

colognes, candles, perfumes. There's rose, tuberose, jasmine, orange, just so much choice.

The scents on sale here probably do come from the plants and flowers printed on the labels.

But if you take, say, sandalwood, a base scent for many perfumes,

the biotech industry has found ways of replicating its smell

without felling a single, slow-growing sandalwood tree.

We actually got our start making high-end flavors and fragrances.

So a perfume company would have a particular molecule that's hard to make or very difficult to make.

And we would take a look at that molecule and see if we could reprogram a yeast or bacterial cell to make that product for them.

He's head of code base at Ginko Biowow Works,

a company based in Boston that's at the heart of a biotech industrial revolution.
